The eastern nation of India consists of Assam, Tripura, Meghalaya, west Bengal, Mizoram, Manipur, and Nagaland while the western region consists of Gujrat, Rajasthan and Maharashtra. The process of unification or accession of eastern and western provinces of India were technically different.

Following are the two major differences in the challenges of nation building in eastern as well as western India:-

1. The most difficult part of nation building in western India was the princely state of Junagarh in present day Gujrat. It was a hindu majority state ruled by a muslim ruler – Nawab Mohd Mahanat khan who wanted to join Pakistan in 1947. But Junagarh acceded through a plebiscite held in 1948. Hence the challenge in western India was the overtly ambitious princely states and their Nizams. While in eastern India, the challenge was to bring different tribes and communities sharing different cultures and practices under one roof. The area of seven sisters (eastern states) consists of more than 200 communities and each with a stake in their land.

2.  The second difference was the attitude of the neighborhood. India shared border with Pakistan in both eastern as well as western parts of the country. But the decisive part of Pakistan was on the west side, so the challenge was to cope up with the new neighbor. The eastern Pakistan ( present day Bangladesh) got majorly ignorance of the urdu speaking western Pakistan which later led to formation of Bangladesh in 1971. The problem here was the large influx of migrants from war ridden Myanmar which hindered our process of nation building.
